.application filed May 27,

To all whom 'it may conce'im: Be it known that I, "Wim-,IAM N3. ORounnn', a resident ot Jersey City, in the county'of Hudson and State rof New Jersey, have-invented certain new and useful .Improvements in Pencil-Lead Holders, of which the following is a specification.

This invention relates ina general way to handwritinginstruments wherein lead is the substanceemployed for producing the desired llnanuscript, andit especially appertains to holders of the magazine type that' are desi ned to contain a supply of pencil leads, a apted to be manually positioned in the `tip o f 'the Pholder and projected therev from, for use one at :1 time in succession.

Primarily, the invention has for its object to produce .a writing insti-fument oi the type mentioned having an ejector so mounted therein as topermit the employment of a comparatively long pencil lead in a casing of ordinary size, or optionally a Casin of reduced longitudinal dimension with a ead` ot' customary length.

Another object is the production Ao t' a writing' instrument of the character set forth including an ejectorrand a protective carrier therefor conjointly engaging a pencil lead guide, that will comet-therewith in feeding =the lead out of: the holder.l

A further 'object is the provision ot a writing',instrument of the naturedescribed, from which the pencil lead vcan be projected through the said guide by merely turning' the tip or pointthereot', so as to draw' out the said ejector with its carrier acting as a slidable impeller and support. j

Still another object is to provide a writ-` inninstrument ot the class referred to em- 40 bodying an alternative, construction to the above, in which the guide will be stationary, and the lead-'advanced thereinioy the ejector, upon translating' the' carrier thereof from the'rear end ot1 the holder. i A still turtheuobject is .to supply a'writing instrument ot the genus alluded to, comhin'ng both of the preceding cpnstructions,"

n such a manner that the projection of the y la lead may be eilected turning, at option, sojjjfjther the guide or the ejector-carrier, from i holders point; Y

the opposite ends otl the holder respectively, 'and if desired, the guide and the carrier simultaneously.

An additional object is to devisea pracu tical pencil lead holder composed of hut few parts, easily constructed and readily joined together, involving no co'nplex arrangement nor intricate mechanism, not liablev to get outjof order, besides being characterized by strength, and susceptible fof low cost of 60 manufacture.

' Other objects and 'advantages 'of the invention will become apparent as the specification proceeds. -f

With the aforesaid objects in view, the invention consists of the novel combinations 'and arrangements of parts hereinafter de# l scribed in. their ypreferred embodiments, pointed out. in the subjoined'. claims, and illustrated on the annexed dra-wing, wherein like parts are designated by the same reference characters4 throughout the several. Views. f

iiifo that it Will turn therewith ,Whenever the said lmember is rotated relatively to the l I fl 'i i Back of the pencil lead in the tube 18, is

' ani-'ejector 21, consisting of a slender rod 'fittingthe bore of the tube. This ejector,

it iis -iinderstood, slidingly engages the tubu- 4 laiigsiyuide, in order to push the lead therethrough and cause it to project out of' the opening-ll, as wanted,forpurposes of writing, i-loth the guide and the ejector may be of same 'length las the lead, or approxicentral axisf'lhe tubeA -foin'iing the carrier -the ejector is directed.

hasl abottom' 23, to which the rearend of theejector is attached, and forwardly the 'mouth of the latter-nanied tube takes over the inner end of the guide 18, into which l The g'uideis externally threaded, as at 24, and engaged by a corresponding internal thread 25, in the' said. mouth of the tubular carrier.

Preferably', the'before' mentioned carrier 22 is made of polygonal contour, thatv is, With-a plurality of ontwardly-disposed faces 28, arranged to '-.bear` slidingly upon inwardly-presented portions 29, of the fluted or corrugated tubing thatforms the magazine 10. The fabes 28 and bearing portions 29, it Will be noted, are shown asbeing flat or straight in outline, but this is notan essential feature, as these parts could easily be given some other shape that would answer the same requirements. Taken together, the bearing portions 29 constitute for the carrier 22, a confining` space or chamber 3O,.vvhich be closed at the outer end by a traiisverse partition 3l to 'prevent disassociatioii of the carrier.fromfthe lead guide.` y v v Y Due to the construction and arrangement of parts 'new' particularly described, it will be seen that4 the guide 18. containing the lead 5, the aligned ejector 21. the carrier 22 thereof receive mutual supportfrom the magazine chamber 30, while permitting a contemporaneous movement of the -operative elements inv an axial plane of the holder.

,As will be observed, the pencil lead is projected outwardly by .the ejector whenever the conical member 2 is rotated relatively to the casing' i, causing' the tubular ,guide 18,

through the action ofl the screw-thread con` nection 24, 25,'to slide the carrier 22 forwardly, from its recess in the magazine. The alternative embodiment of the inven- Ba, all formed integrally tion represented by' Figs; lV tolllll, inl, elusive, comprises a casingl", having -a tal' pering end 2a, terminating in a tipor point i" with one another; '1i The usual opening Ll is provided in thel tip, 4-70 for '.the lead lthe opposite end of the casingilu contains a nr gazine 10,r similar to i that previously'desciil d', having peripheral pockets ll', the inner extremities 1 2 of Which are directed laterally outuard to support 75 the corresponding' ends of the extra pencil leadsthat .will be stored in 'the magazine. As in the before described construction, -the latterI is covered by a cap 13, formed with a flange 14, that extends over the outer ends Vofthe pockets 11, and having also a bead vedge of t e casing..

' In this modified embodiment of the in- Vention, the tubular lead-guide, designated by the reference symbol 18, is fixed within the pointed. end of' the casing 1", so that it is devoid of any capacity for. independent rotative ,movement lnteriorly. however, there is no change in the structure,y as lii'st .90 mentioned, thev tube 18a having a plain axial bore adapted to receive the ejector 2l,

Exteriorly, the said tube or tubular guide' 18 is formed with a plurality of faces, as 24", adapted to engage a correspondingly- 95. faced passage 25, in a hollow or tubular carrier 22". This modified form of carrier has a plain bottoin'23, to which the ejector is, secured endwise, in the manner and for the purpose hereinbefore explained.

the carrier 22"l along the mouth of the tubular guide, in order to advance the ejector 21 through the latter, to feed 'the lead 5 outward, in the mannerrequired. ".lo that Los end, the carrier 22u is externally threaded,- as at 35, and made to engage an internallythreaded portion 36, of'a rotatable member 37, centrally fitted in the magazine l0. The member 37 is preferably tubular, and is irc prevented from" having', any longitudinal movement relatively to the magazine, by means of a circumferential retaining clasp 38, which may consist of`a simple wire ring; lodged in semi-circularA grooves 39, 4:0, rel 115 spectively' formed in opposite portions of the magazine l() and of the rotatable inem-` ber 37. Outwardly, the-member is'circiilar and ,fitted to revolye within bearingr poi?-` tions 29, projecting there around from the 120 fluted tubing of which the iiia-g'azine is coniposed. rlhe clasp which is preferably a split, eXpansib-le ring', is` lodged in :one of the Agfrooves. for instance 40, in a compressed state, that is` with its ends closed together, and after the member 37 is pushed into place withi'n the inner walls l() of the magazine, this ring expands automatically and engages the companion groove l39 so that further axial iiioveiiient of the member 37 is pre- 130 vented, nnleee` an exceseive strain ie applied thereto.

Rotation of the member 37, over the carn rier 22 tor the ejector, is readilyv eii'ected through the instrunientalitjvY of the cap i3'. As shown, the cap, in the present rnodii'icz.- tionis provided on the under side with a socket e3, engaging a, plug or head fri, tightly entered in or forming part of the outer end of the rotatable member. The socket and the ping, it. wi l be noticed. are ot polygonal coniignration, being respeetively formed with a. plurality of lia-t facce 45, 46, that are interengaged and coe-ct in revolving the member 37, and the parte controlled thereby, whenever the cap 13 ie turned.

lt is now apparent that when a vmovement of rotation is imparted to the cap "i3, in the said lnodied torni of the holder, the same is immediately transmitted to the member 37, which in'turn Slides the carrier 2&2, causing it to advance over the .iixed tubelSi. and concomitanllgg7 urging forward the pencil lead therein thru the agency of the ejector The effect' is identical with that obtained by turningthe tip of the holder in the structure hereinbetore described.

Fignree VVll'l and 1X represent a structure embodying; essentially the 'two modes of construction alread)1 described. this Structure, the casing; or the holder iS the same as in the tiret described construction, and theretore is denoted. blv-the reference numeral l. As 'in the tiret instance, this casing` is Shown provided with a rotatable conical member 2. having' a tip 3, in the end or' which is 'the openingT 4f.. tor the .pencil lead The casing; and its conical member are i'nteriitted 'for rotation by means of the ridges 6 and l", as previously set. forth. ln this second Inodiicatioinya magazine l0 is employed, which differs` in. Some respecte from the one forming part of thev preceding` cons'trnet-itons.' The magazine lOlL preferably' consiste of a. cylindrical body having' number ot longitudinal bores 1l, wherein the extra pencil leads can be stored. This cylindrical bod-, is titte-d .in the rear end of the casing; ll so as to be rotatable therein, and is arranged to hear at its inner end upon a` partition '19, that replaces the outwardly-turned extremities; of the pockets in the first torrn ot' `the nao'anine. it the outer end, the magazine l0 ie surrounded) by a llang'e (8, arranged to bear upon the edge of the` casing, at the rear terminal..
